Answer 2

If α,β are the roots of x²+px+q=0 and also of x^2n+p^n x^n+q^n=0 and if α/β,β/α are the roots of x^n+1+(x+1)^n = 0, then n must be *If one root of x²+px+12=0 is 4 while the equation x²+px+q=0 has equal roots then q= The quadratic equation whose roots are (√2+√3 i)/(√2-√3 i) and (√2-√3 i)/(√2+√3 i) is k>0 and the product of the roots of the equation x²-3kx+2e^2logk-1=0 is 7 then the sum of the roots is * If α,β are the roots of the equation x²-2x+3=0, then the equation whose roots are P=α³-3α²+5α-2 and Q=β³-β²+β+5 is A screw gauge gives the following reading when used to measure the diameter of a wire. Main scale reading : 0 mm, Circular scale reading : 52 divisions, Given that 1 mm on main scale corresponds to 100 divisions of the circular scale. The diameter of wire from the above data is : The radius of a uniform wire is r=0.021 cm. The value π is given to be 3.142. What is the area of cross-section of the wire up to appropriate significant figures.
